“…Robert & Mahamat Ali, ( 2005) pointed out that around cities such as Ndjamena; the high demand for fuelwood threatens the sustainability of supply. Nwilo et al, (2020) noted that vegetation in the northwest and the northeast of Nigeria including the region of Lake Chad declined by 2.18% from 1984 to 2000 and by 2.02% from 2000-2016. The causes included agricultural activities such as extensive grazing, and annual cropping, other uses of the trees such as for fuelwood, charcoal, panelling and woodwork and variations in climate (Nwilo et al, 2020).…”

Such exploitation poses risks to the conservation of the whole flora in these and other tropical and sub-tropical regions (Rukangira Ernest, 2001), (Ribeiro et al, 2017).…”

This study on the leguminous plant Sesbania tchadica has made it possible to highlight its description, specification and identification in N'Djamena region S. tchadica (Sesbania Sesban Merr. (L)) is an annual tree that measures more than 4 meters in height. This species is abundant especially in Ndjamena. In most of the district of Ndjamena, S. tchadica was the most common type. S. tchadica shows a rapid early growth and grows well in various soils especially sandy siltstone and silty shale. The local inhabitants use the species in many ways: as a medicine, a livestock feed, for improving soil fertility, for fuelwood and to repel desert encroachment. In this study, various academic publishing websites like Science Direct, Springer Nature, some online international plant databases, and other national data herbaria from the republic of Chad were used to identify, describe and summarize the research literature on Sesbania Sesban. This paper also describes the morphological characteristics observed in Sesbania Sesban from the republic of Chad and its taxonomy to assist in future program evaluations.

“…Moderate Resolution Imaging Spectroradiometer (MODIS) and Sentinel-2 datasets had been used to monitor vegetation and land cover changes from 2005 and 2015 respectively (Jin & Sader, 2005;Schug et al, 2020;Xin et al, 2012). Although non-optical techniques are also used in LULC mapping especially where clouds are frequent (Nicolau et al, 2021), optical remote sensing has long been and is promising as a systematic and cost effective way of monitoring bare ground cover and gain (Barrett et al, 2020;Dematte et al, 2009;Hansen et al, 2014;Nwilo et al, 2020). For LULC classes detection, either full pixel or subpixel scheme is used for the image classification using statistical, regression, expert classifier, artificial neural networks, and other more sophisticated algorithms (Daldegan et al, 2019;Schug et al, 2020).…”

This paper estimates bare area gain detected using cloud free Landsat 7 (ETM+) and Landsat 8 (OLI) in Botswana. From 2002 to 2020, agricultural fields shrunk by 76.4%, while built-up increased by 49.2%, and bare areas increased from 3.32% to 7.03% (or 111.7%). There is a significant seasonal change in bare area detected reaching maximum during the dry season when there is little or no ground cover. In this study, the seasonality of bare area gain was overcome by only considering a bare area pixel to contribute to bare area gain if it exists during both the winter and summer months. The probability of bare area detection was 75.0% and probability of false detection 13.3% respectively. The 13% false detection tended to be built-up areas which had similar spectral characteristics as bare areas since most built-up areas have no ground cover. The bare area gain is driven by the high population growth rate of 3.4%. From 2001 to 2017, the population of the study area has increased by 34% and now accounts for 47% of the population of Botswana.

“…Sand traps the incoming solar radiation during the day, which leads to a rise in the heating of the Earth's surface. This, in turn, imposes extremely austere conditions that lead to the deterioration of the abundance of vegetation [12]. The circular carbon economy (CCE) is an integrated system that leans on reducing CO 2 emissions and manage them through an environmental and economical integrated management system that works on modern technologies [13].…”

Circular Carbon Economy (CCE): A Way to Invest CO2 and Protect the Environment, a Review

et al. 2021

Increased levels of carbon dioxide have revolutionised the Earth; higher temperatures, melting icecaps, and flooding are now more prevalent. Fortunately, renewable energy mitigates this problem by making up 20% of human energy needs. However, from a “green environment” perspective, can carbon dioxide emissions in the atmosphere be reduced and eliminated? The carbon economic circle is an ideal solution to this problem, as it enables us to store, use, and remove carbon dioxide. This research introduces the circular carbon economy (CCE) and addresses its economic importance. Additionally, the paper discusses carbon capture and storage (CCS), and the utilisation of CO2. Furthermore, it explains current technologies and their future applications on environmental impact, CO2 capture, utilisation, and storage (CCUS). Various opinions on the best way to achieve zero carbon emissions and on CO2 applications and their economic impact are also discussed. The circular carbon economy can be achieved through a highly transparent global administration that is supportive of advanced technologies that contribute to the efficient utilisation of energy sources. This global administration must also provide facilities to modernise and develop factories and power stations, based on emission-reducing technologies. Monitoring emissions in countries through a global monitoring network system, based on actual field measurements, linked to a worldwide database allows all stakeholders to track the change in greenhouse gas emissions. The process of sequestering carbon dioxide in the ocean is affected by the support for technologies and industries that adopt the principle of carbon recycling in order to maintain the balance. This includes supporting initiatives that contribute to increasing vegetation cover and preserving oceans from pollutants, especially chemicals and radioactive pollutants, which will undoubtedly affect the process of sequestering carbon dioxide in the oceans, and this will contribute significantly to maintaining carbon dioxide at acceptable levels.
